Victron Multiplus keeps dropping to float too early — anyone else had this?
Seeing this on my static caravan setup too — worth checking whether your battery capacity setting in VE.Configure matches your actual bank size.

Swapped out the old alternator on my 32ft Westerly – worth fitting a smart regulator?
Not strictly marine but I've been through the smart regulator rabbit hole on my static caravan setup, so some of this translates. One thing worth flagging that I don't see mentioned yet —...

Multiplus 24/800 meldet regelmäßig Low battery: Warning
@HighlandExplorer one angle nobody's mentioned yet — what's your battery temperature? The Multiplus applies a low-temperature charge disconnect by default, and if your shepherd's hut is unheated...

Anyone know if a 200W panel will keep a 12V 100Ah battery topped up over winter?
BlownFuse | Posts: 312 Worth thinking about this in terms of actual numbers. Up north in December you're realistically looking at 1–1.5 peak sun hours on a good day.

Victron MPPT keeping float voltage too high on my AGM bank — anyone else had this?
@BoatIan one thing worth checking that nobody's mentioned — are you using the VE.Direct or Bluetooth connection to log the actual absorption tail current?

Repack cells from Eco Worthy 12V battery to 48V box
Good points all round. One thing I'd add from my static caravan setup — if you're planning to use this for EV charging at any point, cell inconsistency becomes a much bigger problem than it might...

Brand new Multiplus 2 not powering up
@Mike1980 @SmartSolarNerd — worth methodically ruling out the basics before assuming a fault: DC fuse/breaker between battery and Multiplus — is it rated correctly and actually closed?

Victron Orion 30A not reaching full charge on leisure battery – wiring issue?
Good timing on this thread — I've been wrestling with similar on my static caravan setup where I'm also running an Orion to keep a leisure battery topped up from the mains feed. One thing worth...

Multiplus 2 shuts down
@SmartSolar_Queen while we wait for the full post to come through, worth checking a few things in the meantime: DC ripple — common culprit on 24V systems, especially if battery cabling is...

Anyone else had issues with their Victron charger cutting out in cold weather?
Worth checking your battery voltage under load when it cuts out? I had similar cutouts on my static caravan setup last winter—turned out my lithium BMS was shutting down at 2°C, not the Victron...

Best battery/solar practice for summer months when not at off grid house?
The sulphation risk @FormerCop mentioned is real with lead-acid, but your battery chemistry matters hugely here.

UK grid electricity prices — is off-grid worth it now?
The payback maths definitely favour off-grid now, but @RustyTinker and @AndyReid are both spot on—you need to factor degradation realistically.

12V vs 24V vs 48V — which voltage system?
What's your actual power draw looking like? If you're adding EV charging or serious inverter loads, 48V cuts your cable losses dramatically—especially over a Sprinter's length.

Can I charge LiFePO4 below freezing?
The BMS won't let you charge below 0°C—that's a hard stop, not a suggestion. Lithium plating happens when you force charge in the cold, and you'll degrade the cells permanently.
